Will Pippa Middleton’s online impersonator succeed where Her Royal Hotness failed? Pippa Tips, the Twitter account that parodies the Duchess of Cambridge’s sister’s life tips, is publishing a book to coincide with the birth of Pippa’s niece or nephew in June. It’s called What to Expect When One is Expecting: A Posh Person’s Guide to Pregnancy and Parenting.

Readers can prepare for more of the pearls of wisdom to which Pippa Middleton could only aspire. Her book, Celebrate, a guide to seasonal entertaining, was bought by Penguin for well over £400,000, a sum unheard of for a first-time writer, but it sold only 2,000 copies on its release in the autumn.

Despite priceless festive tips such as “because of their size, turkeys are perfect for feeding large gatherings”, bookshops spotted the turkey on their shelves and cut its price by 75 per cent in the run-up to Christmas. Other tips suggested that, when in need of ice, “make batches of your own and store in freezer bags” and explained how to play conkers.

Spotting the public needed more helpful direction in the basics of life, the spoof Pippa Tips started on Twitter, telling 40,000 followers to “save time by doing things more quickly,” or to “stay dry by staying indoors”.

Henry Lord, of Icon Books, which publishes the guide on June 6, reckons the book will be greeted with more enthusiasm than its muse’s tome. “We’re expecting a huge buzz,” he said. “It’s very light, very satirical, but also a valuable guide to motherhood.” The identity of the account’s creator is a closely guarded secret but that might change soon. “We may draw the curtain back on that at some point,” Lord revealed.
